Rat Control

We have a dairy farm and have a rat problem. Aside from fixing holes in walls and setting out poison and traps, what is another way to take care of this problem? Another farmer told us about using lime. Any and all suggestions welcomed. Thanks so much!

I've heard of farmers using a 44 Gallon drum, water in the bottom, and then a plank.
The plank goes from outside the outer rim into the centre of the drum, and it's either too slippery for them to grip, or on a fulcrum so that when the rat walks onto the plank is drops down, the rat slides off into the drum, and them can't get out.

Will a GP or similar be able to handle rats up to coyotes? We have rabbits and just moved to the country and are concerned that our stock will be killed off by any number of predators in the area. Should we add a rat terrier or 2? Our plan is the have goats, pigs, chickens, and rabbits. Thanks in advance.

I had a cat who was amazing at rodents. She was a small medium-length fur tortoiseshell with a 2/3 length tail. Rats, Townshend's ground squirrels, wood rats. rabbits, fox squirrels, voles- she'd get them all and generally eat what she caught. She would take care of herself for a week at a time if I was gone, and come running up when I drove in to say hello and go through the meeting ritual. Female cats in general stay closer to home. She made living and gardening on the edge of the wild possible. (ever have a pack rat move in with you, or nightly squirrel soccer games with walnuts in the attic?) She took care of all that, and mostly left the birds alone; over 15 years I had ample time to observe her hunting.
I met a Schipperke dog who was a rodent specialist. They originally controlled rats on river boats. He was all business and kept rats and gophers off 5 acres. I'd always thought the breed was a yappy old lady dog, but I guess they go crazy in a city apartment. (I can relate) This one came up to me, looked me in the eye, and seemed to say, "good to meet you, I'm on duty" and resumed his rounds. Not sure what I would do with a cat that turned out to be useless, but I might find it in me to be a force for selection. (take the beast to the high desert to play with the raptors and coyotes?)

A major deterrent would be to get rid of nesting and cover, remove any old piles of trash and brush, had rats terrible at my sons farm, cleared about an acre of old overgrown pasture to where we could keep it mowed, there's still a few rats but their numbers are down enough to keep them under control with conventional methods.

You need big dogs for coyotes and I mean big (100 lb.+) GP, Catahoula Cur, and other "LGD" breeds and you need more than one since a pack of coyotes can take out even these large guys.
For rats and small predators the rat terrier is a fair choice so you might need several different breeds to get the entire set of "jobs" done.
Cats and dogs can mix on occasion. In my case any cat that did come around would either be up a tree or dead meat as soon as my LGD's spotted it. (they hate cats)
I have a Pit Bull Terrier, a Catahoula and a Boxer and a Donkey, the donkey can take out three coyotes at a time. We have a pack of about 20 coyotes in our area and they don't come onto our land. (I consider that a combination of being on top of the mountain, the fencing and the LGD/ Donkey combo, along with luck)

If you want coyote control without keeping a big dog, you might invite a predator hunter to reduce the population. Hunting coyotes is a fairly popular sport here. I don’t understand it myself. I hunt for meat. I would kill a problem animal, but I wouldn’t enjoy it. Possums are my biggest problem. I’ve caught them killing chickens. Live traps work pretty well. I live in town so can’t shoot them.
